To all whom it may concern:

lie it known that I, NIGOLASIQIHN, engineer, subject of the. Grand Duke of Luxemhurg, residing at Diidelingcn, in the Grand Duchy of luixemburg, have invented new and useful Improvements in Preliminary Heaters, of which the following is a specification.

This invention consists of an apparatus for utilizing the heat of the exit gases from large gas engines in a tubular boiler with double. heatingjacket.

in eontradistinction to the already known apparatuses of this type, the present invention effects an increased utilization of the heat of the exit gases, more particularly as, in the preferred form of the invention, the heat is made useful for the cleansing of the water which serves to feed the boiler tubes. For this purpose, according to the present invention a water purifier is interpolated between the preliminary heating acket and the tubes of the boiler, to assist in preventing incrustation in the boiler. In another constructional form the water is passed through the. cooling acket of the cylinder as well as through the jacket and the tubular system of the boiler.

The invention is illustrated in the accompanying drawings, in which- Figure 1 shows the left, and Fig. 2 the rightlialf of a mechanism constructed according to this invention. Figs. 3 and 4 illustrate a second modification, and vFigs. 5 and (S a third modification of the invention.

in that illustrated in Figs. 3 and 4, the water is cleansed in a water purifier to assist in preventing incrustatimi and then passed through the cooling jacket of the cy inder, then through the jacket of the preliminary healer into a reservoir and finally it is forced from this jacket through a tubular system placed in the preliminary heater to the place or" consumption.

i-iccording to the third modification illustrutcd in Figs. 5 and (3, the water passes first through the jacket of the preliminary heater, then through the water purifier, then through the cylinder jacket, and finally through the tube complex of the preliminary heater to the place of consumption.

Referring first to Figs. 1 and 2, here the impurified water flows from the storage tank a through the pipe 0 to the jacket la of the tubular boiler 9', which serves in the well known manner for preliminary heating of the water. From this point the Water fioivs through a pipe 7) into the water purifier a after having absorbed a portion of the heat of the gases which pass fr m the cylinders of the gas engine through the pipe (1 into the boiler. From the water purifier, the water reaches the receptacle t and is then forced through the pump 2 and the pipe a into the tubular systems of the boiler 1', where it is brought into contact with the. exit gases of the engine g. These gases escape from the boiler through the pipe g into the fine 2'. The water which has ab sorbed while in the tubes a further considerable amount of the heat of the gases, flows from the boiler 7' through the pipe w preferably to a boiler system b.

in Figs. 3 and 4, 1 indicates the crude water receptacle from which the water flows into the Water purifier a. The purified water passes into the cistern at from which it is forced by the pump 2 into a purified water receptacle 3. From this point it tiows means of the pipe t through the jacke the cylinders g, and from thence throir jacket 7?. of the preliminary heater. It .5 slightly warm water then flows through the pipe 5 into a water cistern 6, and from this is forced through the pump 7 and the tube a into the tubes of the preliminary heater, which is arranged in the boiler r. From these tubes the water finally flows through the pipe w to the point of consumption, for instance the boiler installation I), Z) Where it is converted into steam. The exit gases from the gas motor fiow, as already described in the case of the modification illustrated in Figs. 1 and 2, through the tube (Z, around the bundle of tubes 3 placed in the boiler r, and finally through the tube 3 in order to escape into the fine 1'.

According to the third modification illustratcd in Figs. 5 and 6, the water tlows from the crude Water container 8 by means of the tube 9 firstly through the mantle h and then passes through the tube 10 to the water purifier a. lihe purified water collects in the cistern :5 and is forced by the pump 11 into the pure Water cistern 12, which is placed at a height. From thence the water flows through the cooling jackets of the cylinders g from which it is driven through a tube 13 into the cistern 4. From this place llll the pump forces the Water by means of the tube u through the complex of tubes placed in the boiler 1*, and from thence through the pipe as to the place of consumption, for instance the boiler 6, Z). The track of the escaping gases is the same as that described for the previously illustrated example.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that What I claim is:

In combination, a gas engine cylinder provided with a Water jacket, a boiler provided also With a Water jacket, means for passing relatively cold Water into said engine jacket, means for leading Water through said engine jacket into said boiler jacket, means for leading Water through said boiler acket into the interior of said boiler, and means for passing exhaust gases from said cylinder through said boiler.

In testimony whereof I have signed my name to this specification in the presence of tWo subscribing Witnesses.
